Abstract
An optical imaging lens set includes a first lens element with an object-side surface of a convex part in a vicinity of the optical axis, a second lens element with an image-side surface of a concave part in a vicinity of its periphery, the first lens element being glued to the second lens element to eliminate an air gap, a third lens element with an object-side surface of a concave part in a vicinity of its periphery, a fourth lens element and a fifth lens element of plastic material, ALT being the total thickness of the five lens elements and Gmax being the max value of the air gap from the first lens element to the fifth lens element so that ALT/Gmax≤2.2.
Claims16
An optical imaging lens set, from an object side toward an image side in order along an optical axis comprising:
- an aperture stop, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element, said first lens element to said fifth lens element each having an object-side surface facing toward the object side as well as an image-side surface facing toward the image side, wherein:
- said first lens element has an object-side surface with a convex portion in a vicinity of the optical axis;
- said second lens element has an image-side surface with a concave portion in a vicinity of its periphery and is glued to said first lens element without an air gap;
- said third lens element has an object-side surface with a concave portion in a vicinity of its periphery;
- and
- said fourth lens element and said fifth lens element are made of an plastic material,
- wherein, the optical imaging lens set exclusively has five lens elements with refractive power, ALT is the total thickness of the five lens elements and Gmax is the max value of the air gaps from the first lens element to the fifth lens element so that ALT/Gmax≤2.2.
